Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EDSTL950/7 is determined by the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 7 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Header Type & Orientation: The 90° right-angle configuration with male pins and 4-side shrouding must be preserved for form-factor compatibility.
• Voltage Rating: The 300 V UL rating establishes the minimum electrical performance threshold.
• Contact Tail Length: The 0.138" (3.50mm) tail length is critical for PCB insertion depth and solder joint formation.
• Housing Material: Polyamide (nylon) construction ensures thermal and chemical compatibility.
• Compliance Status: RoHS compliance is required for regulated applications.

The substitute part 796644-7 (TE Connectivity AMP Connectors) meets all critical substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the EDSTL950/7 and 796644-7 are active production components with full RoHS compliance. The 796644-7 offers an extended operating temperature range (-40°C ~ 110°C versus -30°C ~ 105°C) and is rated for 15 A current per UL specifications, providing additional performance margin in high-current applications. Both parts carry identical ECCN and HTSUS classifications, confirming regulatory equivalence. Selection between these parts should be based on availability, lead time, and application-specific temperature or current requirements.

Frequently Asked Questions (FAQ)

Q: Can 796644-7 be used as a direct replacement for EDSTL950/7 in existing designs?

A: Yes. Both parts share identical pitch (5.00mm), position count (7), header orientation (90° right angle), contact tail length (3.50mm), and shrouding configuration. Mechanical and electrical compatibility is confirmed.

Q: What are the key differences between these two parts?

A: The 796644-7 features an extended operating temperature range (-40°C to 110°C versus -30°C to 105°C) and includes a specified current rating of 15 A. The housing material differs slightly (PA66 nylon 6/6 versus standard PA nylon), though both are polyamide-based. The 796644-7 specifies tin contact mating finish and copper alloy contact material.

Q: Are both parts RoHS compliant?

A: Yes. The EDSTL950/7 is ROHS3 Compliant, and the 796644-7 is RoHS Compliant. Both meet regulatory requirements for restricted substance elimination.

Q: What is the significance of the contact tail length specification?

A: The 0.138" (3.50mm) contact tail length determines the insertion depth into PCB through-holes and the solder joint formation depth. This dimension must remain consistent across substitute parts to ensure proper mechanical engagement and reliable solder connections.

Q: Can these parts be used interchangeably in high-temperature applications?

A: The 796644-7 supports operation up to 110°C, providing a 5°C margin above the EDSTL950/7 maximum of 105°C. For applications approaching or exceeding 105°C, the 796644-7 is the preferred selection.
