Weidmüller 1775302001 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1775302001 is a 9-position terminal block header with male pins, shrouded design, and 0.200" (5.08mm) pitch in 90° right-angle configuration. This component is part of the Omnimate SL series and is designed for through-hole solder termination applications requiring IEC-rated current handling of 27.5A at 400V.

The 1775302001 carries an Obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Substitute Part Grouping Explanation

Substitution eligibility for the 1775302001 is determined by strict equivalence across the following critical parameters:

Electrical Performance: Current rating (IEC: 27.5A), voltage rating (IEC: 400V), and contact material (Copper Alloy)
Physical Configuration: 9 positions, 0.200" (5.08mm) pitch, 90° right-angle orientation, male pins with 4-side shrouded design
Termination & Mounting: Solder termination, through-hole mounting type
Environmental & Compliance: Operating temperature range (-50°C ~ 100°C), UL94 V-0 flammability rating, RoHS compliance, REACH unaffected status

The substitute part 1780480000 meets all these criteria and is therefore a direct functional equivalent.

Engineering Selection Recommendations

The 1780480000 is the direct substitute for the obsolete 1775302001. Both components are manufactured by Weidmüller within the Omnimate SL series and share identical electrical ratings, physical dimensions, and compliance certifications.

The primary distinction is product status: 1775302001 is Obsolete, while 1780480000 is Active. This makes 1780480000 the recommended choice for new designs and ongoing production requirements.

Both parts carry RoHS compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards. The UL94 V-0 flammability rating is maintained across both variants, supporting applications requiring high-temperature stability and fire resistance.

The contact tail length differs between the two parts (1.50mm versus 3.20mm), but this represents a manufacturing variation within the same product family and does not affect functional compatibility in standard through-hole solder applications.

Frequently Asked Questions (FAQ)

Q: Can 1780480000 be used as a direct replacement for 1775302001 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 9 positions, 0.200" (5.08mm) pitch, 90° right-angle orientation, 27.5A IEC current rating, and 400V IEC voltage rating. The contact tail length variation does not affect compatibility in standard PCB through-hole mounting.

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

A: The contact tail length (1.50mm for 1775302001 versus 3.20mm for 1780480000) is a manufacturing specification that affects solder joint formation depth. Both lengths are within acceptable ranges for standard through-hole solder termination and do not impact electrical performance or mechanical fit in typical applications.

Q: Why is 1775302001 listed as Obsolete?

A: Product obsolescence is determined by the manufacturer based on production lifecycle decisions. The 1780480000 is the active production equivalent and is recommended for all new applications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical compliance status: RoHS Compliant, REACH Unaffected, UL94 V-0 flammability rating, and EAR99 export classification. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for both variants.

Q: What packaging options are available?

A: The 1775302001 is available in standard packaging, while 1780480000 is supplied in Bulk packaging. Packaging format does not affect component functionality or electrical performance.
