Molex 0901471308 Equivalent & Substitute Parts

Part Overview

The Molex 0901471308 is an 8-position receptacle connector with 0.100" (2.54mm) pitch, designed for through-hole PCB mounting with gold-plated mating contacts. This connector operates across -55°C to 105°C with a 3A current rating and 350V voltage rating, serving applications in automotive, general purpose, lighting, medical, and telecommunications sectors. The part is active and ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when they maintain functional compatibility through matching core electrical and mechanical parameters: connector type (receptacle), contact configuration (8 positions, female socket), pitch (0.100"), mounting method (through-hole solder), and fastening type (push-pull). Substitutes may vary in insulation height, contact post length, material composition, and contact finish specifications within acceptable tolerances for board-to-board connectivity.

Engineering Selection Recommendations

Direct Equivalents (Receptacle, Gold Finish):

TE Connectivity 5-534237-6 and 534237-6 maintain receptacle configuration with 8-position 0.100" pitch and gold mating finish. The 5-534237-6 variant is RoHS compliant; 534237-6 is non-compliant. Both operate -65°C to 125°C, exceeding the original temperature range. Current rating is 2A, which is lower than the 3A specification of the Molex part. These are suitable for applications where 2A current capacity is sufficient.

Amphenol ICC 75915-308LF is a receptacle with matching gold finish, 8 positions, and 0.100" pitch. RoHS compliant with UL94 V-0 flammability rating. Operating temperature and current rating are not specified in available data. Insulation height and contact post length match the original specification.

Harwin M20-7820842 is a receptacle with gold finish, 8 positions, and 0.100" pitch. ROHS3 compliant with 3A current rating and 1000V voltage rating, exceeding original electrical specifications. Operating temperature range is -40°C to 105°C, which covers the upper portion of the original -55°C to 105°C range but does not extend to -55°C.

Alternate Finish Options (Tin Mating Contact):

Amphenol ICC 75915-408LF is a receptacle with tin mating finish instead of gold. Maintains 8 positions, 0.100" pitch, and through-hole solder termination. RoHS compliant. Use when gold finish is not required and cost optimization is a priority.

Samtec SSW-108-03-T-S is a receptacle with tin mating finish, forked contact type, 8 positions, and 0.100" pitch. ROHS3 compliant with 4.7A per contact current rating and -55°C to 105°C operating temperature matching the original. Contact post length is 0.394" (10.00mm), significantly longer than the original 0.114" (2.90mm), requiring PCB design accommodation.

Header Alternatives (Different Connector Style):

Sullins PPPC081LFBN-RC and PPTC081LFBN-RC are header connectors (not receptacles) with 8 positions and 0.100" pitch. PPPC081LFBN-RC has gold mating finish; PPTC081LFBN-RC has tin finish. Both are ROHS3 compliant with 3A current rating. Operating temperature is -40°C to 105°C. These are compatible only if the application permits header-to-receptacle mating rather than receptacle-to-plug mating.

Compliance Considerations:

For applications requiring ROHS3 compliance, select from: Molex 0901471308, TE Connectivity 5-534237-6, Amphenol ICC 75915-308LF and 75915-408LF, Harwin M20-7820842, Sullins PPPC081LFBN-RC and PPTC081LFBN-RC, or Samtec SSW-108-03-T-S.

For applications requiring RoHS compliance without ROHS3 specification, TE Connectivity 534237-6 and 535541-6 are acceptable alternatives, though 535541-6 has a shorter insulation height (0.265" vs. 0.335") and longer contact post (0.125" vs. 0.114").

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 534237-6 be used as a direct replacement for Molex 0901471308?

A: Functionally, yes. Both are 8-position receptacles with 0.100" pitch, gold mating finish, and push-pull fastening. However, 534237-6 is RoHS non-compliant, whereas the Molex part is ROHS3 compliant. Current rating is 2A versus 3A on the original. If your application requires ROHS3 compliance or 3A current capacity, use TE Connectivity 5-534237-6 (RoHS compliant variant) instead.

Q: What is the difference between Amphenol 75915-308LF and 75915-408LF?

A: The primary difference is mating contact finish. 75915-308LF has gold plating; 75915-408LF has tin plating. Both are 8-position receptacles with 0.100" pitch and RoHS compliance. Select based on contact finish requirements: gold for corrosion resistance and signal integrity in sensitive applications, tin for general-purpose applications where cost is a consideration.

Q: Why is Samtec SSW-108-03-T-S listed as a substitute if it has a much longer contact post?

A: SSW-108-03-T-S meets the core substitution criteria: 8-position receptacle, 0.100" pitch, through-hole solder termination, and push-pull fastening. The 0.394" contact post length (versus 0.114" on the original) is a mechanical difference that requires PCB design verification. This part is suitable only if your PCB layout can accommodate the longer post depth. Verify board thickness and component placement before selection.

Q: Can Sullins PPPC081LFBN-RC replace the Molex receptacle?

A: PPPC081LFBN-RC is a header connector, not a receptacle. Headers and receptacles have opposite mating interfaces. This part is compatible only if your application uses receptacle-to-header mating (header plugs into this part). If your original design uses receptacle-to-plug mating, this substitution is not compatible. Verify your mating connector type before selection.

Q: Which substitute offers the best temperature range coverage?

A: TE Connectivity 5-534237-6 and 534237-6 both operate -65°C to 125°C, providing the widest temperature range. However, if ROHS3 compliance is required, Harwin M20-7820842 (-40°C to 105°C) and Samtec SSW-108-03-T-S (-55°C to 105°C) are compliant alternatives. SSW-108-03-T-S matches the original -55°C lower limit exactly.

Q: Is voltage rating a critical factor in selecting a substitute?

A: The original Molex part is rated 350V. Harwin M20-7820842 is rated 1000V, providing higher voltage capability. Sullins parts are rated 250V, which is lower than the original. If your application requires 350V or higher, verify the substitute voltage rating. For applications operating below 250V, Sullins parts are acceptable. TE Connectivity and Samtec parts do not specify voltage rating; contact manufacturers for clarification if voltage rating is critical.

Q: What is the significance of contact finish thickness specifications?

A: Contact finish thickness affects durability and mating cycle life. The original Molex part specifies 30.0µin (0.76µm) gold on mating contacts and 118.1µin (3.00µm) tin on posts. TE Connectivity parts specify 150.0µin (3.81µm) tin on posts, providing thicker post plating. Samtec and Harwin parts do not specify thickness. Thicker finishes generally provide longer service life in high-cycle mating applications. For static or low-cycle applications, finish thickness differences are not critical.
