Substitute Part Grouping Explanation

Substitution of the Weidmüller 1641980000 is determined by strict equivalence across the following critical parameters:

8-position configuration with 4 positions per level and 2 levels
4.6mm (0.138") pitch spacing
Vertical through-hole mounting orientation
Male pin header with 4-side shrouding
Solder termination
UL94 V-0 flammability rating
Tin contact mating finish
10 A current rating (UL) and 300 V voltage rating (UL)

The On Shore Technology Inc. OSTVO081250 meets all critical substitution criteria. While minor variations exist in housing material composition, contact material specification, and insulation height, these differences remain within acceptable engineering tolerances for equivalent functional performance in the specified application category.

Engineering Selection Recommendations

The On Shore Technology OSTVO081250 serves as a direct functional equivalent to the obsolete Weidmüller 1641980000. Selection of the OSTVO081250 is supported by:

Identical electrical specifications across all critical parameters (pitch, position count, current and voltage ratings)
Matching mechanical configuration (vertical through-hole, male pins, 4-side shrouding)
Equivalent safety certifications (UL94 V-0 flammability rating)
Active product status ensuring ongoing availability and supply chain continuity
ROHS3 compliance providing regulatory alignment for new designs
Extended operating temperature range (-30°C ~ 105°C) offering broader environmental compatibility compared to the original part

The OSTVO081250 is suitable for direct replacement in existing applications and for incorporation into new designs requiring 8-position, 4.6mm pitch terminal block headers with vertical through-hole mounting.

Frequently Asked Questions (FAQ)

Q: Can the OSTVO081250 be used as a direct replacement for the Weidmüller 1641980000 in existing PCB designs?

A: Yes. Both parts share identical pitch spacing (4.6mm), position configuration (8 positions, 4 per level), mounting type (vertical through-hole), and electrical ratings (10 A UL, 300 V UL). PCB footprints designed for the 1641980000 are compatible with the OSTVO081250.

Q: What are the differences between these two parts?

A: The primary differences are housing material composition (PBT vs. thermoplastic), contact material (copper alloy vs. brass), and insulation height (0.953" vs. 0.862"). The OSTVO081250 also features an extended operating temperature range (-30°C to 105°C vs. -20°C to 100°C) and carries ROHS3 compliance certification.

Q: Does the OSTVO081250 meet the same safety standards as the original part?

A: Yes. Both parts carry UL94 V-0 flammability ratings and REACH Unaffected status, ensuring equivalent safety and environmental compliance.

Q: Is the OSTVO081250 available in the same packaging format?

A: The OSTVO081250 is supplied in bulk packaging, whereas the original part packaging specification was not provided. Confirm packaging requirements with your supplier for volume orders.

Q: Are there any thermal performance differences between these parts?

A: The OSTVO081250 supports a wider operating temperature range (-30°C ~ 105°C) compared to the Weidmüller 1641980000 (-20°C ~ 100°C), providing greater thermal margin for applications operating at temperature extremes.
