Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 1937651 are qualified based on the following critical parameters that must match or exceed the original specification:

• Electrical Compatibility: 7 positions, 4.6mm pitch, 8A minimum current rating (UL), 300V minimum voltage rating (UL)
• Mechanical Compatibility: Vertical orientation, male pins, shrouded (4 side) design, through-hole solder termination
• Material & Safety: UL94 V-0 flammability rating, RoHS compliance, MSL 1 (Unlimited)
• Physical Dimensions: Contact tail length and insulation height within acceptable tolerance ranges for PCB mounting

The following substitute parts meet these criteria:

• Molex 0395011007 (Eurostyle ESE 39501 series, tin finish)
• Molex 0395011507 (Eurostyle ESE 39501 series, gold finish)
• Molex 0395016007 (Eurostyle ESE 39501 series, green housing, tin finish)
• Molex 0395016507 (Eurostyle ESE 39501 series, green housing, gold finish)
• Amphenol Anytek OQ0712500000G (06-350 series, green housing, tin finish)

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing support, addressing the obsolescence status of the Phoenix Contact 1937651. Selection among substitutes should be based on the following criteria:

Molex Eurostyle ESE 39501 Series (0395011007, 0395011507, 0395016007, 0395016507): These parts maintain full electrical and mechanical compatibility with the original specification. The Molex series offers ROHS3 compliance and active product status. Housing color (black vs. green) and contact finish (tin vs. gold) are available options. Gold-plated contacts (0395011507, 0395016507) provide enhanced corrosion resistance for applications requiring extended service life or harsh environments. Tin-plated contacts (0395011007, 0395016007) are suitable for standard applications.

Amphenol Anytek OQ0712500000G: This part exceeds the original current rating at 10A per position and operates across an extended temperature range (-40°C to 115°C). The contact tail length matches the original specification exactly (0.138" / 4.60mm), while insulation height is identical. This option is suitable for applications requiring higher current capacity or wider operating temperature margins.

All substitute parts carry UL94 V-0 flammability rating and RoHS3 compliance, meeting regulatory requirements for modern electronics manufacturing.

Frequently Asked Questions (FAQ)

Q: Can I use Molex 0395016007 as a direct replacement for Phoenix Contact 1937651?

A: Yes. The Molex 0395016007 meets all critical electrical and mechanical parameters: 7 positions, 4.6mm pitch, 8A current rating, 300V voltage rating, vertical orientation, male pins, shrouded design, and through-hole solder termination. The primary difference is housing color (green vs. black) and contact tail length tolerance (0.140" vs. 0.134"), which do not affect functional compatibility on standard PCB layouts.

Q: What is the difference between tin and gold contact finishes?

A: Tin-plated contacts (0395011007, 0395016007, OQ0712500000G) provide cost-effective performance for standard applications. Gold-plated contacts (0395011507, 0395016507) offer superior corrosion resistance and are recommended for applications with extended storage periods, high-humidity environments, or where contact reliability over extended service life is critical.

Q: Why does Amphenol Anytek OQ0712500000G have a higher current rating?

A: The Amphenol part is rated at 10A per position versus 8A for the original and Molex substitutes. This higher rating reflects the design specifications of the Amphenol 06-350 series and does not indicate incompatibility. The part remains suitable for applications requiring 8A or less.

Q: Are there any dimensional differences I should account for in PCB design?

A: Contact tail length varies slightly: Phoenix Contact 1937651 is 0.134" (3.40mm), Molex parts are 0.140" (4.66mm), and Amphenol OQ0712500000G is 0.138" (4.60mm). Insulation height is consistent across all parts at approximately 0.360-0.362" (9.14-9.20mm). These variations are within standard PCB through-hole tolerance ranges and do not require design modification for typical applications.

Q: Which substitute offers the best long-term availability?

A: All listed substitutes are active products from established manufacturers (Molex and Amphenol Anytek). Molex 0395011007 and 0395016007 show the highest current inventory levels (8906 and 8287 units respectively), indicating strong supply chain support.
