MODS-A-6P6C-G Equivalent & Substitute Parts

Part Overview

The MODS-A-6P6C-G is a modular jack connector manufactured by Samtec Inc., designed for 6-position 6-contact (6p6c) applications including RJ11, RJ12, RJ14, and RJ25 configurations. This connector features a 90° right-angle orientation with through-hole solder termination and unshielded design, rated for Cat3 performance. The product is currently obsolete, making identification of equivalent and substitute parts essential for ongoing system support, maintenance, and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MODS-A-6P6C-G is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Jack
• Contact configuration: 6p6c (RJ11, RJ12, RJ14, RJ25)
• Orientation: 90° right-angle
• Mounting: Through hole
• Termination: Solder
• Shielding: Unshielded (primary requirement)

Secondary Compatibility Criteria:

• Operating temperature range (minimum -25°C, maximum 90°C)
• Contact material and finish specifications
• Housing material composition
• RoHS and regulatory compliance

Substitute parts are grouped into two categories based on electrical rating compatibility:

Category A - Cat3 Rated (Direct Equivalents): Parts maintaining Cat3 performance specification, suitable for applications with identical electrical requirements.

Category B - Cat4 Rated (Enhanced Performance): Parts with Cat4 rating provide superior performance characteristics and are backward compatible with Cat3 applications.

Category C - Shielded Variants: Parts with shielded design differ from the unshielded primary specification and are listed for reference only where EMI mitigation is required.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Cat3 Unshielded - Direct Equivalents):

5555165-1 (TE Connectivity) and 5520250-3 (TE Connectivity) are the preferred substitutes for MODS-A-6P6C-G. Both maintain Cat3 electrical rating, unshielded configuration, and through-hole solder termination. Both parts are active products with RoHS compliance and unlimited moisture sensitivity level (MSL 1). The 5555165-1 offers superior inventory availability (24,260 units) and is recommended as the primary replacement. The 5520250-3 provides an alternative with equivalent electrical and mechanical specifications.

Secondary Substitute (Cat4 Unshielded - Enhanced Performance):

0432496001 (Molex) provides Cat4 performance rating, which exceeds the Cat3 requirement of the original part. This connector is suitable for applications where enhanced electrical performance is beneficial. The part is active, ROHS3 compliant, and available in tray packaging. The extended operating temperature range (-40°C to 85°C) provides broader environmental compatibility compared to the original specification.

Alternative Substitute (Unshielded - Alternate Manufacturer):

SS-6466-NF-A431 (Stewart Connector) offers unshielded 6p6c configuration with through-hole solder termination. This part is active and ROHS3 compliant. The thermoplastic housing differs from the original PBT material. This option is suitable where Stewart Connector supply chain integration is preferred.

Not Recommended for Direct Substitution:

SS-6466-NF-50 (Stewart Connector) features shielded design, which differs from the unshielded specification of MODS-A-6P6C-G. This part is suitable only for applications requiring EMI shielding and should not be used as a direct replacement without circuit design review.

Frequently Asked Questions (FAQ)

Q: Can 0432496001 (Molex Cat4) be used in place of MODS-A-6P6C-G (Samtec Cat3)?

A: Yes. Cat4 rating provides enhanced performance specifications and is backward compatible with Cat3 applications. The electrical and mechanical interfaces are identical. No circuit modifications are required.

Q: What is the difference between 5555165-1 and 5520250-3?

A: Both are TE Connectivity Cat3 unshielded 6p6c connectors with identical electrical and mechanical specifications. The primary difference is inventory availability (5555165-1 has 24,260 units versus 5520250-3 with 2,200 units) and packaging (5555165-1 in tray, 5520250-3 in tray). Both are suitable substitutes.

Q: Why is SS-6466-NF-50 listed if it is shielded?

A: SS-6466-NF-50 is listed for reference as a shielded alternative. It is not a direct substitute due to shielding differences. Use this part only if EMI mitigation is required and circuit design permits shielded connector integration.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are RoHS compliant (either RoHS or ROHS3 certified), matching the compliance status of MODS-A-6P6C-G.

Q: What is the operating temperature consideration for substitution?

A: MODS-A-6P6C-G operates from -25°C to 90°C. All substitute parts operate from -40°C to 85°C. The substitute parts have a lower maximum temperature (85°C versus 90°C). Verify application requirements do not exceed 85°C continuous operation.

Q: Can I use these substitutes interchangeably on the same PCB?

A: Yes, for unshielded variants (5555165-1, 5520250-3, 0432496001, SS-6466-NF-A431). All maintain identical 6p6c pin configuration, 90° right-angle orientation, through-hole mounting, and solder termination. Physical footprint compatibility is maintained across all unshielded options.

Q: What packaging options are available?

A: Substitute parts are available in tray packaging (0432496001, 5520250-3, 5555165-1, SS-6466-NF-50) or tube packaging (SS-6466-NF-A431). Verify packaging requirements for your procurement and assembly processes.
