Engineering Selection Recommendations

TE Connectivity Direct Equivalents:

The TE Connectivity 6-146250-3 is the manufacturer-recommended active replacement for the obsolete 1-104433-3. This part maintains identical core specifications including 26 positions, 2-row configuration, 0.100" pitch, through-hole mounting, and push-pull fastening. The 6-146250-3 is currently in active production status with ROHS3 compliance, providing long-term availability and regulatory alignment. The part is suitable for direct substitution in new designs and production continuity applications.

The TE Connectivity 6-146264-3 is an alternative direct equivalent with identical electrical and mechanical parameters. This part features kinked pin termination instead of press-fit, offering different assembly characteristics while maintaining functional compatibility. ROHS3 compliance and active product status support its use in modern applications.

Cross-Manufacturer Alternatives:

Molex C-Grid 70280 and C-Grid 70287 series connectors (part numbers 0010897263, 0010977265, 0702871060, 0702871158, 0702871256) provide functionally equivalent solutions with identical position count, pitch spacing, and mounting configuration. All Molex alternatives are ROHS3 compliant and active products. Minor variations in contact length and insulation material (LCP with glass fill) do not affect functional interchangeability for standard board-to-board applications.

Amphenol ICC (FCI) BERGSTIK® series connectors (part numbers 68691-126HLF, 77313-422-26LF, 77313-822-26LF) offer equivalent functionality with identical position count and pitch spacing. These parts feature phosphor bronze contacts and extended operating temperature range (-65°C to 130°C), providing enhanced thermal performance. All Amphenol ICC alternatives are RoHS compliant and active products.

Compliance Considerations:

The original 1-104433-3 is RoHS non-compliant. All recommended substitutes are RoHS compliant (ROHS3 or RoHS Compliant), supporting regulatory requirements for new designs and production transitions. All substitute parts maintain UL94 V-0 flammability rating and moisture sensitivity level 1 (unlimited).

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 6-146250-3 directly replace the 1-104433-3 in existing designs?

A: Yes. The 6-146250-3 maintains identical electrical and mechanical specifications including 26 positions, 2-row configuration, 0.100" pitch spacing, through-hole mounting, and push-pull fastening. The primary difference is product status: the 6-146250-3 is active production while the 1-104433-3 is obsolete. The 6-146250-3 is the manufacturer-recommended replacement.

Q: What are the key differences between TE Connectivity and Molex alternatives?

A: TE Connectivity alternatives (6-146264-3, 6-146250-3) maintain identical specifications within the AMPMODU Mod II series. Molex alternatives (C-Grid 70280 and 70287 series) provide equivalent functionality with minor variations in contact length (0.320" versus 0.318") and insulation material composition (LCP with glass fill versus thermoplastic). These variations do not affect functional interchangeability for standard applications.

Q: Are Amphenol ICC (FCI) BERGSTIK® connectors compatible with the 1-104433-3?

A: Yes. BERGSTIK® series connectors (68691-126HLF, 77313-422-26LF, 77313-822-26LF) provide functional equivalence with identical position count, row configuration, and pitch spacing. Contact material differs (phosphor bronze versus copper alloy) and operating temperature range is extended (-65°C to 130°C versus -65°C to 105°C). These differences support enhanced performance in thermal applications.

Q: What is the significance of RoHS compliance in selecting a substitute?

A: The original 1-104433-3 is RoHS non-compliant. All recommended substitutes are RoHS compliant (ROHS3 or RoHS Compliant). RoHS compliance is mandatory for new product designs and production transitions in regulated markets. Selection of RoHS-compliant alternatives ensures regulatory alignment and long-term supply chain viability.

Q: Do all substitute parts support the same current and voltage ratings?

A: The 1-104433-3 is rated for 3A current and 30VAC voltage. TE Connectivity alternatives maintain these ratings. Molex alternatives do not specify voltage or current ratings in available documentation but maintain identical contact geometry and material specifications. Amphenol ICC (FCI) alternatives specify 3A per contact current rating with no voltage specification. For applications requiring specific voltage ratings, TE Connectivity alternatives provide explicit specification alignment.

Q: What termination options are available across substitute parts?

A: The original 1-104433-3 features press-fit and solder termination. TE Connectivity 6-146250-3 offers solder termination only. TE Connectivity 6-146264-3 offers kinked pin and solder termination. Molex alternatives offer either solder or kinked pin and solder termination. Amphenol ICC (FCI) alternatives offer solder termination. Selection depends on specific assembly process requirements.

Q: Are there inventory considerations when selecting a substitute?

A: Current inventory levels vary across substitute parts. TE Connectivity 6-146250-3 has 870 units in stock. Molex alternatives range from 764 to 1118 units. Amphenol ICC (FCI) alternatives range from 791 to 1013 units. Inventory availability should be evaluated against production timeline requirements and long-term supply strategy.
