Molex 0901471230 Equivalent & Substitute Parts

Part Overview

The Molex 0901471230 is a 30-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications. This through-hole, gold-plated connector operates across -55°C to 105°C and supports 3A current at 350V, making it suitable for automotive, medical, telecommunications, and general-purpose applications. The part is currently active and ROHS3 compliant. Substitute parts may be required due to inventory constraints, design revisions, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0901471230 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Must be receptacle with female socket contacts
• Position Count & Pitch: Must maintain 30 positions at 0.100" (2.54mm) pitch for mechanical and electrical compatibility
• Mounting & Termination: Through-hole solder termination required for PCB integration
• Contact Finish: Gold plating on mating surface for corrosion resistance and signal integrity
• Electrical Performance: Current and voltage ratings must meet or exceed application requirements
• Operating Temperature Range: Must support the thermal envelope of the target application
• Mechanical Compatibility: Insulation height and contact geometry must allow proper mating with corresponding connectors

The TE Connectivity AMP Connectors part 2-534237-8 qualifies as a substitute based on matching core parameters: 30-position receptacle configuration, 0.100" pitch, through-hole solder termination, gold mating finish, and compatible mechanical dimensions.

Parameter Comparison

Engineering Selection Recommendations

Molex 0901471230 is the primary specification. This part is active, ROHS3 compliant, and REACH unaffected, making it suitable for regulated applications including medical and automotive sectors.

TE Connectivity 2-534237-8 serves as a functional substitute with the following considerations:

• Mechanical compatibility is confirmed across pitch, position count, mounting type, and termination method
• Operating temperature range is extended (-65°C ~ 125°C vs. -55°C ~ 105°C), providing broader thermal capability
• Current rating is reduced (2A vs. 3A); applications requiring 3A continuous current must remain on the primary part
• RoHS compliance status differs: the TE part is non-compliant, restricting use in regulated markets
• REACH status is vendor-undefined for the TE part, requiring clarification for restricted substance compliance

Selection should prioritize the Molex part for new designs and regulated applications. The TE substitute is applicable only where current requirements do not exceed 2A and RoHS/REACH compliance is not mandated.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-534237-8 replace the Molex 0901471230 in all applications?

A: No. While mechanical and electrical compatibility exists for most parameters, the TE part has a reduced current rating (2A vs. 3A) and is RoHS non-compliant. Use only in applications where current does not exceed 2A and regulatory compliance is not required.

Q: What are the critical dimensions for connector compatibility?

A: The 0.100" (2.54mm) pitch and 30-position configuration are fixed. Insulation height (0.335" vs. 0.340") and contact post length (0.114" vs. 0.115") are within acceptable tolerance for mating with standard connectors in this series.

Q: Are there differences in contact finish specifications?

A: Both parts feature gold mating finish. The Molex part specifies 15.0µin (0.38µm) thickness, while the TE part specifies 30.0µin (0.76µm). The TE part has thicker gold plating, which may provide enhanced durability in high-cycle mating applications.

Q: What is the impact of the different operating temperature ranges?

A: The TE part supports -65°C to 125°C versus -55°C to 105°C for the Molex part. For applications within the Molex range, both are acceptable. For extended temperature operation, the TE part offers additional margin.

Q: How do the post finishes differ?

A: The Molex part uses tin post finish (118.1µin / 3.00µm), while the TE part uses tin-lead (150.0µin / 3.81µm). This affects soldering characteristics and long-term reliability in lead-free assembly processes.

Q: Is the TE part suitable for medical device applications?

A: The TE part's RoHS non-compliance and undefined REACH status make it unsuitable for medical device applications without explicit regulatory approval. The Molex part is the appropriate choice for medical applications.
