Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 147340-1 are qualified based on the following critical parameters that ensure functional and mechanical interchangeability:

Electrical Compatibility Criteria:

• Connector type: Receptacle
• Contact type: Female socket
• Number of positions: 50
• Pitch - mating: 0.100" (2.54mm)
• Number of rows: 2
• Row spacing - mating: 0.100" (2.54mm)
• Contact finish - mating: Gold
• Contact finish thickness - mating: 30.0µin (0.76µm)
• Operating temperature range: -65°C ~ 125°C
• Contact shape: Square

Mechanical Compatibility Criteria:

• Mounting type: Through hole, right angle
• Fastening type: Push-pull
• Contact length - post: 0.115" (2.92mm)

All four substitute parts (66527-025, 66527-025LF, 66527-525, 66527-525LF) from Amphenol ICC (FCI) meet these core parameters. The substitutes are manufactured under the Dubox™ series and maintain active product status, providing long-term availability advantages over the obsolete 147340-1.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and RoHS-Compliant Applications:

Select either 66527-025LF or 66527-525LF. Both parts are RoHS compliant and carry active product status, ensuring long-term supply chain stability. The 66527-525LF variant includes an insulation plug feature. These parts are suitable for automotive, general purpose, industrial, and telecommunications applications.

For Legacy System Replacement:

Select 66527-025 or 66527-525 for direct substitution in existing assemblies where RoHS compliance is not a requirement. Both maintain the same electrical and mechanical specifications as the obsolete 147340-1. The 66527-525 variant includes an insulation plug feature.

Compliance Considerations:

The 66527-025LF and 66527-525LF variants are RoHS compliant with REACH unaffected status, providing regulatory advantages for applications subject to environmental directives. The 66527-025 and 66527-525 variants are RoHS non-compliant but carry REACH affected status, similar to the original 147340-1.

All substitute parts are classified under ECCN EAR99 and HTSUS 8536.69.4040, maintaining the same export classification as the original component.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 66527 series connectors directly replace the TE Connectivity 147340-1?

A: Yes. The 66527-025, 66527-025LF, 66527-525, and 66527-525LF connectors are electrically and mechanically compatible with the 147340-1. All parts share identical specifications for connector type, contact configuration, pitch, row spacing, mounting type, contact finish, and operating temperature range.

Q: What is the difference between the 66527-025 and 66527-525 variants?

A: The 66527-525 and 66527-525LF variants include an insulation plug feature. The 66527-025 and 66527-025LF variants do not include this feature. All other electrical and mechanical specifications are identical.

Q: What is the significance of the "LF" designation in part numbers 66527-025LF and 66527-525LF?

A: The "LF" designation indicates lead-free construction and RoHS compliance. These variants are suitable for applications subject to RoHS directives and environmental regulations. The non-LF variants (66527-025 and 66527-525) are RoHS non-compliant.

Q: Are there any dimensional differences between the 147340-1 and the 66527 series substitutes?

A: The insulation height differs slightly. The 147340-1 has an insulation height of 0.238" (6.05mm), while all 66527 series substitutes have an insulation height of 0.240" (6.10mm). This 0.002" (0.05mm) difference is within typical PCB layout tolerances and does not affect functional compatibility.

Q: What is the inventory availability of these substitute parts?

A: Current inventory levels are: 66527-025 (1103 pcs), 66527-025LF (4600 pcs), 66527-525 (673 pcs), and 66527-525LF (906 pcs). The 66527-025LF variant offers the highest stock availability.

Q: Are the substitute parts suitable for automotive applications?

A: Yes. The 66527 series connectors are rated for automotive, general purpose, industrial, and telecommunications applications. All variants carry a UL94 V-0 material flammability rating and 1250V voltage rating.

Q: What is the contact material composition of the substitute parts?

A: The 66527 series connectors use brass contacts with tin post finish (100.0µin / 2.54µm thickness) and gold mating finish (30.0µin / 0.76µm thickness). The original 147340-1 uses phosphor bronze contacts with tin-lead post finish.

Q: Can the 147340-1 be used interchangeably with the 66527 series in existing assemblies?

A: Yes, for direct replacement in existing assemblies. The electrical and mechanical compatibility is confirmed across all critical parameters. The slight insulation height difference (0.002") does not impact assembly or performance.
