Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 66951-014 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 14 positions at 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole solder termination for board-to-board connectivity
• Contact Finish - Mating: Gold plating on mating surfaces
• Operating Temperature: -65°C to 125°C range
• Insulation Material: Polyester, glass-filled construction

The identified substitutes maintain these core parameters, ensuring mechanical and electrical compatibility in applications originally designed for the 66951-014.

Engineering Selection Recommendations

66951-014LF (Amphenol ICC - Direct Substitute)

The 66951-014LF is the primary substitute for the obsolete 66951-014. Both parts are manufactured by Amphenol ICC within the same Dubox™/BergCon® PV™ series and share identical mechanical and electrical specifications. The 66951-014LF is currently in active production status with higher inventory availability (3096 pcs vs. 1109 pcs). The key distinction is RoHS compliance: the 66951-014LF is RoHS Compliant with REACH Affected status, whereas the original part is RoHS non-compliant. This substitute is recommended for new designs and ongoing production requiring RoHS-compliant components.

1-534237-2 (TE Connectivity AMP Connectors - Cross-Manufacturer Substitute)

The TE Connectivity 1-534237-2 provides cross-manufacturer compatibility for applications where Amphenol ICC parts are unavailable. This connector maintains the same 14-position, 0.100" pitch, through-hole solder termination, and gold-plated mating contacts. Notable differences include contact material (phosphor bronze vs. brass), insulation height (0.340" vs. 0.325"), and contact post length (0.115" vs. 0.142"). The 1-534237-2 is ROHS3 Compliant and rated for 2A current. This part is suitable for applications where cross-manufacturer substitution is acceptable and mechanical envelope tolerances permit the 0.015" insulation height variation.

Frequently Asked Questions (FAQ)

Q: Can the 66951-014LF be used as a direct replacement for the 66951-014?

A: Yes. Both connectors are manufactured by Amphenol ICC and share identical mechanical and electrical specifications. The primary difference is RoHS compliance status. The 66951-014LF is the active production equivalent and is recommended for all new applications.

Q: What are the mechanical differences between the 66951-014 and the TE Connectivity 1-534237-2?

A: The 1-534237-2 has an insulation height of 0.340" compared to 0.325" for the 66951-014, a difference of 0.015". Additionally, the contact post length differs (0.115" vs. 0.142"), and the contact material is phosphor bronze rather than brass. These differences may affect board layout and mating force characteristics.

Q: Is the TE Connectivity 1-534237-2 suitable for applications originally designed for the 66951-014?

A: The 1-534237-2 maintains the same pitch, position count, and gold-plated mating contact finish, making it mechanically and electrically compatible for most applications. However, the dimensional variations in insulation height and contact post length should be evaluated against specific board layout and mating requirements.

Q: What is the difference between the 66951-014 and 66951-014LF packaging?

A: The 66951-014 packaging is not specified in the original documentation. The 66951-014LF is supplied in tube packaging, which is standard for active production components.

Q: Are there current rating differences between these connectors?

A: The 66951-014 and 66951-014LF do not specify a current rating. The TE Connectivity 1-534237-2 is rated for 2A. Current capacity should be evaluated based on application requirements and contact gauge specifications.

Q: Which substitute should be selected for new designs?

A: The 66951-014LF is recommended for new designs as it is the direct Amphenol ICC equivalent in active production with RoHS compliance. The TE Connectivity 1-534237-2 is suitable when cross-manufacturer sourcing is required or when Amphenol ICC parts are unavailable.
