Phoenix Contact 1937664 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1937664 is an 8-position terminal block header with male pins, shrouded on 4 sides, featuring a 0.138" (4.60mm) pitch for vertical through-hole mounting. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The part operates at 8A per position (IEC) and 300V (UL), with solder termination and UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1937664 is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Number of Positions: 8
• Pitch: 0.138" (4.60mm)
• Type: Header, Male Pins, Shrouded (4 Side)
• Header Orientation: Vertical
• Mounting Type: Through Hole
• Termination Style: Solder
• Voltage - UL: 300V
• Material Flammability Rating: UL94 V-0
• Contact Mating Finish: Tin

Acceptable Variation Parameters:

• Current - UL: Substitute parts rated at 8A or higher are acceptable
• Operating Temperature: Substitute parts with equal or wider temperature ranges are acceptable
• Housing Material: Polyamide (PA66) Nylon 6/6 is acceptable as equivalent to Polyamide (PA) Nylon Glass Filled
• Contact Material: Brass or Phosphor Bronze are acceptable alternatives to unspecified contact material
• Product Status: Active status substitutes are preferred for obsolete parts

All five substitute parts meet these criteria and are classified as direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

Molex 0395011008 and TE Connectivity 284514-8 are the preferred substitutes. Both are active products with full UL94 V-0 certification and match all critical electrical parameters. Molex 0395011008 maintains identical current rating (8A) to the original part, while TE Connectivity 284514-8 provides higher current capacity (11A) with equivalent voltage and flammability ratings. Both support the full operating temperature range of -40°C to 110°C.

Secondary Substitutes (Acceptable with Verification):

Würth Elektronik 691321100008 and TE Connectivity 796694-8 are active products meeting all critical substitution criteria. Both provide current ratings of 10A and 11A respectively, exceeding the original 8A specification. Operating temperature ranges are -40°C to 105°C and -40°C to 110°C respectively, both acceptable for standard applications.

Alternative Substitute (Limited Application):

On Shore Technology OSTOQ081250 meets dimensional and electrical specifications but lacks documented UL94 flammability rating and specifies thermoplastic housing material rather than polyamide. This part is suitable only for applications where flammability certification is not a design requirement.

All substitute parts maintain RoHS3 compliance and tin contact mating finish, ensuring compatibility with existing PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher current rating than the original 1937664?

A: Yes. The Phoenix Contact 1937664 is rated at 8A per position (IEC) and 8A (UL). Substitute parts rated at 8A or higher, such as TE Connectivity 284514-8 (11A) and 796694-8 (11A), or Würth Elektronik 691321100008 (10A), are electrically compatible and provide additional design margin.

Q: Are all substitute parts suitable for my application?

A: Substitutes differ in flammability certification and housing material. If UL94 V-0 rating is required, use Molex 0395011008, TE Connectivity 284514-8, TE Connectivity 796694-8, or Würth Elektronik 691321100008. On Shore Technology OSTOQ081250 lacks documented flammability certification and should be used only in non-regulated applications.

Q: What is the difference between the TE Connectivity 284514-8 and 796694-8?

A: Both parts are functionally equivalent with identical electrical specifications (11A, 300V, UL94 V-0). The primary difference is housing color: 284514-8 is green, while 796694-8 is blue. Both support operating temperatures of -40°C to 110°C.

Q: Does the On Shore OSTOQ081250 have the same mounting type as the original part?

A: The On Shore OSTOQ081250 specifies "Solder" mounting type rather than "Through Hole" like the original 1937664. This indicates a different PCB assembly method. Verify your PCB design accommodates solder mounting before selecting this substitute.

Q: Are all substitutes RoHS compliant?

A: Yes. All substitute parts carry ROHS3 compliance certification, matching or exceeding the RoHS compliance status of the original Phoenix Contact 1937664.

Q: What is the contact material difference between substitutes?

A: The original part does not specify contact material. Substitutes use Brass (Molex 0395011008, Würth Elektronik 691321100008, TE Connectivity 796694-8, On Shore OSTOQ081250) or Phosphor Bronze (TE Connectivity 284514-8). Both materials are standard for terminal block applications and provide equivalent electrical performance.
