WR-PHD 61300511821 Equivalent & Substitute Parts

Part Overview

The Würth Elektronik WR-PHD 61300511821 is a 5-position receptacle connector with 0.100" (2.54mm) pitch designed for board-to-board applications. This through-hole mounted connector features gold-plated forked contacts, solder termination, and push-pull fastening. The component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, manufacturing discontinuation, or application-specific availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the WR-PHD 61300511821 with the Adam Tech RS1-05-G is based on equivalence across the following critical parameters:

Electrical Compatibility:

• Identical current rating of 3A
• Identical voltage rating of 250VAC
• Matching contact finish (gold-plated)
• Equivalent contact material properties (copper alloy vs. brass)

Mechanical Compatibility:

• Identical number of positions (5)
• Identical mating pitch (0.100" / 2.54mm)
• Identical mounting type (through hole)
• Identical termination method (solder)
• Identical fastening type (push-pull)
• Equivalent insulation height (0.335" / 8.50mm vs. 0.335" / 8.51mm)
• Identical connector style (board to board)
• Identical contact type (forked)

Compliance & Regulatory:

• Both ROHS3 compliant
• Both REACH unaffected
• Both UL94 V-0 rated
• Identical ECCN and HTSUS classifications

Operational Differences:

• Operating temperature range: WR-PHD supports -40°C ~ 125°C; RS1-05-G supports -40°C ~ 105°C
• Contact length post: WR-PHD 0.122" (3.10mm); RS1-05-G 0.118" (3.00mm)
• Insulation material: WR-PHD uses standard PBT; RS1-05-G uses glass-filled PBT

Parameter Comparison

Engineering Selection Recommendations

Primary Selection - WR-PHD 61300511821: Select the Würth Elektronik WR-PHD 61300511821 when the application requires the extended operating temperature range of -40°C to 125°C. This part is Active status with 1405 units in stock. The standard PBT insulation material and copper alloy contacts provide baseline performance characteristics. ROHS3 compliance and UL94 V-0 flammability rating satisfy regulatory requirements for industrial and consumer applications.

Substitute Selection - RS1-05-G: The Adam Tech RS1-05-G serves as an electrical and mechanical equivalent when the WR-PHD 61300511821 is unavailable. This part is Active status with 3918 units in stock. The RS1-05-G operates within the -40°C to 105°C range, which covers standard industrial and commercial temperature requirements. The glass-filled PBT insulation provides enhanced mechanical rigidity compared to standard PBT. Brass contact material maintains equivalent electrical performance at the specified 3A current and 250VAC voltage ratings. Both parts are ROHS3 compliant and REACH unaffected.

Operational Considerations: The contact length post variation (0.122" vs. 0.118") and operating temperature range difference (125°C vs. 105°C maximum) are the only material deviations. Applications operating continuously above 105°C require the WR-PHD 61300511821. Applications with standard thermal profiles accept either part. The insulation material composition difference (standard vs. glass-filled PBT) does not affect electrical performance but may influence mechanical stress tolerance in high-vibration environments.

Frequently Asked Questions (FAQ)

Q: Can the RS1-05-G replace the WR-PHD 61300511821 in all applications?

A: The RS1-05-G is electrically and mechanically equivalent for applications operating within -40°C to 105°C. Applications requiring sustained operation above 105°C must use the WR-PHD 61300511821 due to its extended temperature rating to 125°C.

Q: What is the difference between copper alloy and brass contacts?

A: Both materials provide equivalent electrical conductivity and corrosion resistance when gold-plated. Brass offers slightly different mechanical properties and cost characteristics. For the specified 3A current and 250VAC voltage ratings, both contact materials perform identically.

Q: Does the contact length post variation affect PCB design?

A: The contact length post difference (0.122" vs. 0.118") is 0.004" (0.10mm). This variation is within standard PCB through-hole tolerance ranges and does not require design modification for either part.

Q: Are both parts suitable for high-reliability applications?

A: Both parts are ROHS3 compliant, REACH unaffected, and UL94 V-0 rated. Both support 3A current and 250VAC voltage specifications. Selection depends on the specific operating temperature requirement and inventory availability.

Q: What is the difference in packaging between these parts?

A: The WR-PHD 61300511821 is supplied in Tray packaging with 1405 units in stock. The RS1-05-G is supplied in Box packaging with 3918 units in stock. Packaging format does not affect electrical or mechanical performance.

Q: Can these connectors be used interchangeably on the same PCB assembly?

A: Yes, both connectors are mechanically and electrically interchangeable on the same PCB when the application temperature profile does not exceed 105°C. The identical pitch (2.54mm), mounting type (through hole), and contact configuration ensure direct substitution without PCB redesign.

Q: What certifications apply to both parts?

A: Both parts carry ROHS3 compliance, REACH unaffected status, and UL94 V-0 flammability rating. Both are classified under ECCN EAR99 and HTSUS 8536.69.4040.
