Molex 0901471304 Equivalent & Substitute Parts

Part Overview

The Molex 0901471304 is a 4-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 automotive, general purpose, lighting, medical, and telecommunications applications. The part is Active status and RoHS3 compliant. Equivalent and substitute parts are identified when mechanical fit, electrical performance, and environmental specifications align within acceptable tolerances for board-to-board rectangular connector applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following parameters: 4-position configuration, 0.100" (2.54mm) mating pitch, through-hole solder termination, female socket contact type, and board-to-board mounting style. All substitute parts listed maintain these core mechanical and electrical specifications. Variations in contact finish thickness, insulation color, contact post length, and material composition are documented but do not preclude functional substitution when electrical and mechanical envelope requirements are met. RoHS compliance status and REACH classification are noted for regulatory consideration but do not affect electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0901471304 is RoHS3 compliant and REACH unaffected. Among substitute parts, 75915-304LF, 75915-804LF, 76308-104LF, 76308-204LF, 89885-304LF, and 89885-304LLF are RoHS compliant. The 534237-2 is RoHS non-compliant and REACH affected, limiting its use in regulated applications. For applications requiring full temperature range coverage (-55°C to 105°C) and specified voltage/current ratings (350V, 3A), the Molex 0901471304 remains the primary specification. The 534237-2 offers extended temperature range (-65°C to 125°C) but reduced current rating (2A) and lacks voltage specification. Amphenol ICC (FCI) Dubox™ series parts (75915-304LF, 75915-804LF, 89885-304LF, 89885-304LLF) and BergCon® series parts (76308-104LF, 76308-204LF) provide RoHS-compliant alternatives with matching mechanical envelopes. Contact finish thickness variations and post length differences must be evaluated against specific PCB design and mating connector specifications.

Frequently Asked Questions (FAQ)

Q: Can 75915-404LF substitute for 0901471304 despite tin mating contact finish? A: 75915-404LF maintains the required 4-position, 0.100" pitch, through-hole solder termination, and mechanical envelope. The tin mating contact finish differs from the gold specification of 0901471304. Substitution is mechanically feasible but introduces contact finish variation that may affect corrosion resistance and contact reliability in specific environmental conditions.

Q: What is the significance of contact post length variation between 0.104" and 0.135"? A: Contact post length affects PCB hole engagement depth and solder joint formation. The 0901471304 specifies 0.114" (2.90mm), while 76308-104LF and 76308-204LF specify 0.135" (3.43mm). Longer posts provide greater engagement but may require PCB design accommodation. Shorter posts in 89885-304LF (0.104") and 89885-304LLF (0.104") reduce engagement margin.

Q: Are 89885-304LF and 89885-304LLF functionally identical? A: Both parts are electrically and mechanically identical. The difference is packaging: 89885-304LF is supplied in bulk, while 89885-304LLF is supplied in tube. Selection depends on inventory management and handling requirements.

Q: Why is 534237-2 listed as a substitute if it is RoHS non-compliant? A: The 534237-2 meets core mechanical and electrical substitution criteria (4-position, 0.100" pitch, through-hole solder termination, female socket, board-to-board style). However, RoHS non-compliance and REACH-affected status restrict its use in regulated markets. It is documented for reference but not recommended for new designs requiring RoHS compliance.

Q: Does mating contact finish thickness affect interchangeability? A: Mating contact finish thickness variations (15.0µin to 39.4µin) are within industry tolerance ranges for 0.100" pitch connectors. These variations do not prevent mechanical or electrical interchangeability but may influence long-term contact resistance and corrosion performance under specific environmental exposure.

Q: Can I use 75915-304LF in automotive applications? A: Yes. 75915-304LF is rated for automotive, general purpose, industrial, and telecommunications applications. It is RoHS compliant and maintains the required 4-position, 0.100" pitch configuration. Verify compliance with specific automotive qualification standards if required by your application.
