Weidmüller 1774852001 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The Weidmüller 1774852001 is an 11-position terminal block header with male pins, shrouded on two sides, featuring a 0.200" (5.08mm) pitch and 90° right-angle through-hole mounting. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts from current manufacturers. Substitute parts must maintain functional compatibility across electrical ratings, mechanical dimensions, and termination characteristics to ensure direct replacement capability in existing circuit designs.

Engineering Selection Recommendations

Direct Pitch-Matched Substitutes (5.08mm):

For applications requiring exact 5.08mm pitch spacing, the following active parts provide direct substitution:

Molex 0395325011: Matches 2-side shroud configuration and 5.08mm pitch. Active product status with ROHS3 compliance. Suitable for standard applications within -40°C to 105°C operating range.
Molex 0395329011 / 0395329511: Provide 4-side shroud configuration with 5.08mm pitch and enhanced current rating (18A UL). Suitable for applications requiring additional mechanical protection. Gold-plated variant (0395329511) available for enhanced contact reliability.
TE Connectivity 1-796638-1: 4-side shrouded, 5.08mm pitch variant with RoHS compliance. Operates to -40°C to 110°C. Suitable for applications requiring copper alloy contacts.
Amphenol PCD ELFH11220: 2-side shrouded, 5.08mm pitch equivalent with PBT housing. Operates to -40°C to 105°C. RoHS compliant.
Amphenol PCD ELFH11210: 4-side shrouded, 5.08mm pitch variant with PBT housing. Operates to -40°C to 105°C. RoHS compliant.

Pitch-Variant Substitutes (5.00mm):

For applications where minor pitch tolerance (5.00mm vs. 5.08mm) is acceptable:

Molex 0395220011: 2-side shrouded, 5.00mm pitch. Active product with ROHS3 compliance. Operates to -40°C to 105°C.
Molex 0395224011 / 0395226011: 4-side shrouded, 5.00mm pitch variants. Extended operating temperature to 140°C (0395224011). ROHS3 compliant.

All substitute parts maintain UL94 V-0 flammability rating and 300V UL voltage specification. Selection should be based on shroud configuration requirements (2-side vs. 4-side), contact finish preference (tin vs. gold), and operating temperature range constraints.

Frequently Asked Questions (FAQ)

Q: Can Molex 0395325011 directly replace Weidmüller 1774852001?

A: Yes. Both parts feature 11 positions, 5.08mm pitch, 2-side shroud configuration, solder termination, and through-hole mounting. Electrical ratings (15A UL, 300V UL) meet the original specification. Operating temperature range (-40°C to 105°C) covers the original -50°C to 100°C specification. Both are RoHS compliant.

Q: What is the difference between 2-side and 4-side shroud configurations?

A: 2-side shrouded headers provide shrouding on two opposing sides, offering basic mechanical protection. 4-side shrouded headers provide shrouding on all four sides, offering enhanced mechanical protection and EMI shielding. Both configurations maintain the same electrical and positional specifications. Selection depends on application-specific mechanical and environmental requirements.

Q: Are 5.00mm pitch parts (Molex Eurostyle ESE 39522 series) compatible with 5.08mm pitch designs?

A: 5.00mm and 5.08mm pitches represent a 0.08mm difference per position. For an 11-position header, cumulative spacing difference is approximately 0.8mm. Compatibility depends on PCB layout tolerance and mechanical constraints. Direct substitution is not recommended without PCB design verification. Use 5.08mm pitch equivalents for guaranteed compatibility.

Q: Which substitute offers the highest current rating?

A: Molex 0395329011 and 0395329511 provide 18A UL current rating, matching the original 18.5A UL specification more closely than other substitutes rated at 15A UL.

Q: What is the significance of contact finish (tin vs. gold)?

A: Tin-plated contacts provide standard electrical performance and cost efficiency. Gold-plated contacts (Molex 0395321511, 0395329511) offer enhanced corrosion resistance and contact reliability in demanding environments. Selection depends on application requirements and environmental exposure.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry RoHS or ROHS3 compliance certification, meeting environmental and hazardous substance restrictions.

Q: What housing materials are used in substitute parts?

A: Substitute parts use Polyamide (PA66), Polybutylene Terephthalate (PBT), or Nylon 6/6 housing materials. All materials meet UL94 V-0 flammability requirements. Material selection affects operating temperature range and mechanical properties but does not impact electrical compatibility.

Q: Can I use a 4-side shrouded part in place of a 2-side shrouded part?

A: Yes, functionally. 4-side shrouded parts provide additional mechanical protection and can be used in applications originally designed for 2-side shrouded headers. Verify PCB layout accommodates the larger shroud envelope before substitution.
