Substitute Part Grouping Explanation

Substitution eligibility for the 929647-04-03-EU is determined by strict alignment with the following core parameters: 0.100" (2.54mm) mating pitch, 3-position single-row configuration, male pin contact type, through-hole solder termination, push-pull fastening, unshrouded breakaway header style, and board-to-board or board-to-cable connectivity. All substitute parts must maintain these electrical and mechanical characteristics to ensure direct functional equivalence in PCB assembly applications.

The identified substitute parts are grouped by manufacturer and series designation while preserving the critical dimensional and electrical specifications. Variations in contact length, insulation height, contact finish composition, and operating temperature ranges are documented but do not preclude substitution when the core mating interface parameters remain constant.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and comply with RoHS and REACH regulatory requirements equivalent to the 929647-04-03-EU. The Molex KK254 series (0022285034) and C-Grid III series (0901200123, 0901200763, 0901200923) provide direct functional equivalence with identical mating pitch and position count. The TE Connectivity AMPMODU Mod II series (826629-3, 826646-3, 826647-3, 826926-3, 826936-3) offers extended operating temperature ranges and higher current ratings (5A) compared to the original specification. The Amphenol ICC BERGSTIK® series (861400031YO8LF) provides an alternative with comparable electrical performance and extended temperature capability.

Selection among substitutes should prioritize alignment with existing PCB footprint requirements, contact length specifications, and insulation material compatibility with the target application environment. Parts with identical contact finish composition (gold mating surface) provide the most direct electrical equivalence. Substitutes with tin-plated mating contacts (Molex 0901200123, TE 826926-3, TE 826936-3) remain functionally compatible but introduce different contact resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 929647-04-03-EU with any of the listed parts without PCB redesign?

A: Substitution without PCB redesign requires verification of contact length, post length, and insulation height dimensions. The 929647-04-03-EU has an overall contact length of 0.845" (21.46mm) with specific mating and post length specifications. Substitute parts exhibit variations in these dimensions. Confirm that the substitute part's contact geometry aligns with your PCB hole pattern and component clearance requirements before implementation.

Q: What is the difference between gold-plated and tin-plated mating contacts?

A: The 929647-04-03-EU features gold-plated mating contacts (10.0µin thickness) for enhanced corrosion resistance and lower contact resistance. Substitute parts with tin-plated mating surfaces (such as Molex 0901200123 and TE 826926-3) provide adequate electrical performance but may exhibit higher contact resistance and reduced corrosion protection in high-humidity or corrosive environments. Gold-plated alternatives (Molex 0901200763, TE 826629-3, TE 826646-3, TE 826647-3) maintain equivalent contact characteristics to the original part.

Q: Are there packaging differences among the substitute parts?

A: Yes. The 929647-04-03-EU is supplied in bulk packaging. Molex 0901200923 is supplied in tray packaging, which may affect procurement logistics and handling procedures. All other substitutes are supplied in bulk packaging consistent with the original part. Verify packaging requirements with your supply chain and assembly processes before part selection.

Q: What is the current rating difference between the 929647-04-03-EU and substitute parts?

A: The 929647-04-03-EU is rated for 2.5A continuous current. Most TE Connectivity AMPMODU Mod II substitutes (826629-3, 826646-3, 826647-3, 826926-3, 826936-3) are rated for 5A, providing higher current capacity. The Molex KK254 (0022285034) and C-Grid III series do not specify current ratings. The Amphenol ICC BERGSTIK® (861400031YO8LF) is rated for 3A. For applications requiring the original 2.5A specification, verify that the substitute part's current rating meets or exceeds your design requirements.

Q: What is the operating temperature range difference?

A: The 929647-04-03-EU operates from -40°C to 105°C. Molex C-Grid III and Amphenol ICC BERGSTIK® parts extend the upper temperature limit to 125°C. TE Connectivity AMPMODU Mod II parts extend the lower temperature limit to -65°C and upper limit to 105°C. For applications operating outside the original -40°C to 105°C range, select a substitute with appropriate temperature specifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are RoHS compliant or ROHS3 compliant, meeting the regulatory requirements of the original 929647-04-03-EU. All parts maintain MSL 1 (Unlimited) moisture sensitivity classification and REACH compliance status consistent with the original specification.
