Engineering Selection Recommendations

TE Connectivity 7-534206-5 (AMPMODU Mod II)

This substitute maintains receptacle connector type with identical pitch and row spacing. The part is ROHS3 compliant and active in production. Operating temperature range extends to -65°C ~ 125°C, providing broader environmental coverage than the Molex part. Current rating is 2A, which is lower than the 3A rating of the main part; this must be evaluated against application requirements. Voltage rating is not specified. Insulation height is 0.320" (8.13mm), slightly lower than the 0.335" (8.51mm) of the main part.

Amphenol ICC 87606-325LF (Dubox™)

This substitute is a receptacle connector with identical pitch, row spacing, and contact geometry. RoHS compliant and active in production. Insulation material is thermoplastic glass-filled, differing from the polyester glass-filled material of the main part. Insulation color is blue rather than black. Current rating and voltage rating are not specified. Operating temperature range is not provided. Contact finish thickness on mating surface is 30.0µin (0.76µm), higher than the main part's 15.0µin (0.38µm).

Sullins PPPC252LFBN-RC (Header, Gold Finish)

This substitute is a header connector rather than a receptacle, with identical pitch and row spacing. ROHS3 compliant and active in production. Current rating is 3A, matching the main part. Voltage rating is 250V, lower than the main part's 350V. Operating temperature range is -40°C ~ 105°C, narrower than the main part. Contact finish on mating surface is gold flash. Contact length on post is 0.126" (3.20mm), longer than the main part's 0.114" (2.90mm).

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 7-534206-5 be used as a direct replacement for the Molex 0901512250?

A: The TE Connectivity part maintains the same connector type (receptacle), pitch (0.100"), row spacing (0.100"), and fastening mechanism (push-pull). However, the current rating is 2A versus 3A for the Molex part. Substitution is permissible only if the application current requirement does not exceed 2A. Voltage rating for the TE part is not specified and must be confirmed with the manufacturer.

Q: What is the difference between receptacle and header connectors in this product line?

A: The Molex 0901512250 and TE Connectivity 7-534206-5 are receptacle connectors, while the Sullins PPPC252LFBN-RC and PPTC252LFBN-RC are header connectors. Receptacles accept mating plugs, while headers provide the mating pins. The choice between receptacle and header depends on the complementary connector type required in the application circuit.

Q: Are the Sullins header connectors compatible with the Molex receptacle connector?

A: The Sullins header connectors (PPPC252LFBN-RC and PPTC252LFBN-RC) have identical pitch (0.100"), row spacing (0.100"), and contact geometry (square phosphor bronze). They are mechanically and electrically compatible for mating with receptacle connectors of the same pitch and configuration. However, the contact post length is 0.126" (3.20mm) versus 0.114" (2.90mm) for the Molex part, which may affect mating depth and stacking height.

Q: What is the significance of contact finish (gold versus tin)?

A: Contact finish affects signal integrity, corrosion resistance, and electrical performance. The Molex 0901512250 features gold-plated mating contacts (15.0µin thickness). The Sullins PPPC252LFBN-RC also has gold finish (flash thickness), while the PPTC252LFBN-RC has tin finish. Gold provides superior corrosion resistance and is preferred for high-reliability applications. Tin finish is acceptable for general-purpose applications with lower environmental stress.

Q: Does the Amphenol ICC 87606-325LF meet the same compliance requirements as the Molex part?

A: The Amphenol ICC part is RoHS compliant. The Molex part is ROHS3 compliant. Both parts have MSL rating of 1 (Unlimited) and ECCN classification of EAR99. REACH status differs: the Molex part is REACH Unaffected, while the Amphenol part is REACH Affected. Compliance verification with specific regulatory requirements is necessary before substitution.

Q: What are the packaging differences among these substitute parts?

A: The Molex 0901512250 is supplied in tube packaging. The TE Connectivity 7-534206-5 and Amphenol ICC 87606-325LF are also supplied in tube packaging. The Sullins PPPC252LFBN-RC and PPTC252LFBN-RC are supplied in tray packaging. Packaging format may affect handling, storage, and automated assembly processes.

Q: Can the operating temperature range differences affect part selection?

A: The Molex part operates from -55°C to 105°C. The TE Connectivity part extends to -65°C ~ 125°C, providing broader coverage. The Sullins parts operate from -40°C to 105°C, which is narrower on the low-temperature end. Selection must align with the application's thermal environment and reliability requirements.
