Molex 0901512204 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0901512204 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 is part of the C-Grid III 90151 series and is actively produced. Substitute parts are identified when equivalent electrical and mechanical specifications are met, enabling component interchangeability in applications where the original part may be unavailable or when design requirements permit alternative contact finishes or series variants.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Connector geometry: 4 positions, 0.100" (2.54mm) pitch, 2-row configuration, square contact shape
Mounting and termination: Through-hole solder termination with push-pull fastening
Contact material: Phosphor bronze construction
Insulation material: Polyester or thermoplastic, glass-filled
Moisture sensitivity: MSL 1 rating

The three identified substitute parts meet these core geometric and material requirements. Variations in contact finish (gold vs. tin), contact finish thickness, insulation height, and operating temperature ranges are secondary parameters that do not prevent functional substitution when the primary mechanical and electrical interfaces are preserved.

Engineering Selection Recommendations

All three substitute parts are actively produced and meet RoHS compliance requirements. Selection between alternatives is based on specific application constraints:

TE Connectivity 5-146762-9 provides the widest operating temperature range (-65°C ~ 125°C) and UL94 V-0 flammability rating. The tin mating contact finish differs from the original gold specification; this part is suitable for applications where contact finish material is not a critical parameter.

TE Connectivity 534206-2 matches the gold mating contact finish of the original part and maintains ROHS3 compliance. Operating temperature range extends to -65°C ~ 125°C. This part provides the closest functional equivalence to the Molex 0901512204 when gold contact finish is required.

Amphenol ICC 87606-302LF maintains gold mating contact finish and identical insulation height (0.335") to the original part. UL94 V-0 flammability rating is provided. This part is suitable for applications requiring thermoplastic insulation material and automotive or industrial environments.

Current rating and voltage rating specifications are fully defined for the Molex 0901512204 (3A, 350V). Substitute parts with unspecified electrical ratings should be evaluated against application requirements before selection.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 5-146762-9 be used as a direct replacement for Molex 0901512204?

A: Geometric and mechanical compatibility is confirmed. The primary difference is the tin mating contact finish versus gold on the original part. Selection depends on whether the application requires gold plating for corrosion resistance or contact reliability in specific environments.

Q: What is the significance of the 0.015" (0.38mm) difference in insulation height between parts?

A: Insulation height affects the overall connector profile and mating stack height. TE Connectivity parts (5-146762-9 and 534206-2) are 0.015" shorter. Verify PCB layout and mating connector clearances before substitution.

Q: Are all substitute parts suitable for automotive applications?

A: Molex 0901512204 and Amphenol ICC 87606-302LF list automotive applications. TE Connectivity parts do not specify automotive applications in the provided data. Confirm application suitability with design requirements.

Q: What is the difference between ROHS3 Compliant and RoHS Compliant designations?

A: Both designations indicate compliance with RoHS directives. ROHS3 refers to the third iteration of the RoHS directive. All parts meet current RoHS requirements.

Q: Does the current rating difference (3A vs. 2A) affect substitution?

A: The Molex 0901512204 is rated for 3A, while TE Connectivity substitutes are rated for 2A. If the application requires 3A current capacity, TE Connectivity parts may not be suitable. Verify actual circuit current requirements.

Q: What packaging differences exist between these parts?

A: Molex 0901512204 and TE Connectivity parts are supplied in tube packaging. Amphenol ICC 87606-302LF is supplied in bulk packaging. Confirm packaging requirements for procurement and handling procedures.
