Engineering Selection Recommendations

Both the Weidmüller 1624920000 and TE Connectivity 796980-2 maintain Active product status and meet all critical electrical and mechanical substitution criteria. Selection between these parts should be based on:

Weidmüller 1624920000: Select when PBT housing material is specified, contact tail length of 0.177" (4.50mm) is required, or operating temperature range of -20°C to 100°C is sufficient. RoHS Compliant certification applies.

TE Connectivity 796980-2: Select when PA66/Nylon 6/6 housing material is acceptable, contact tail length of 0.138" (4.60mm) is compatible with PCB layout, or extended operating temperature range of -40°C to 110°C is required. ROHS3 Compliant certification applies.

Both parts carry identical electrical ratings (15 A UL, 300 V UL), UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level. Mechanical compatibility is confirmed for 2-position, 0.300" (7.62mm) pitch, vertical through-hole applications with shrouded 4-side design.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 796980-2 be used as a direct replacement for Weidmüller 1624920000?

A: Yes, within the constraints of contact tail length and housing material differences. The TE Connectivity part has a shorter contact tail (0.138" vs 0.177") and different housing material (PA66 vs PBT). Verify PCB pad spacing and mechanical clearance requirements before substitution.

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

A: The primary differences are contact tail length (0.138" for TE Connectivity versus 0.177" for Weidmüller), housing material (PA66/Nylon 6/6 versus PBT), and operating temperature range (-40°C to 110°C versus -20°C to 100°C). All electrical ratings, pitch, position count, and flammability ratings are identical.

Q: Are both parts RoHS compliant?

A: Yes. Weidmüller 1624920000 is RoHS Compliant, and TE Connectivity 796980-2 is ROHS3 Compliant. Both meet RoHS requirements.

Q: What is the significance of the different housing materials?

A: Weidmüller uses Polybutylene Terephthalate (PBT) while TE Connectivity uses Polyamide (PA66/Nylon 6/6). Both materials meet UL94 V-0 flammability requirements. Material selection may affect mechanical properties, chemical resistance, and thermal characteristics in specific applications.

Q: Does the contact tail length difference affect electrical performance?

A: No. The contact tail length difference (0.138" versus 0.177") does not affect electrical performance. However, it impacts PCB pad spacing and through-hole depth requirements. Verify compatibility with your PCB design before substitution.

Q: Are both parts suitable for 15 A at 300 V applications?

A: Yes. Both parts are rated for 15 A (UL) and 300 V (UL), making them electrically equivalent for this specification.

Q: What is MSL 1 rating?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life with no special moisture control requirements during storage or handling. Both parts carry this rating.
