Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Würth Elektronik 61300211821 is determined by the following critical parameters:

• Connector type (Receptacle)
• Number of positions (2)
• Pitch specification (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Current rating (3A minimum)
• Voltage rating (250VAC minimum)
• Operating temperature range (-40°C to 105°C minimum)
• Contact finish (Gold plating on mating surface)
• Flammability rating (UL94 V-0)
• Regulatory compliance (ROHS3)

The Adam Tech RS1-02-G meets all substitution criteria as a 2-position, 2.54mm pitch receptacle connector with identical electrical ratings, through-hole solder termination, gold-plated contacts, UL94 V-0 flammability rating, and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the Würth Elektronik 61300211821 and Adam Tech RS1-02-G are active production parts with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Packaging format preference (Bag versus Box)
• Mechanical tolerance requirements for insulation height and contact post length
• Insulation material specification (standard PBT versus glass-filled PBT)
• Contact shape preference (Rectangular versus Square)
• Contact material specification (Copper Alloy versus Brass)

Both parts satisfy the electrical and thermal requirements for board-to-board 2.54mm pitch applications with 3A/250VAC ratings and -40°C to 105°C operating range.

Frequently Asked Questions (FAQ)

Q: Can the Adam Tech RS1-02-G directly replace the Würth Elektronik 61300211821 in existing designs?

A: Yes. Both connectors share identical pitch (2.54mm), position count (2), electrical ratings (3A/250VAC), mounting method (through-hole solder), and operating temperature range (-40°C to 105°C). Mechanical dimensions are equivalent within engineering tolerance.

Q: What are the differences between these two parts?

A: The primary differences are: contact shape (Rectangular versus Square), contact material (Copper Alloy versus Brass), insulation material composition (standard PBT versus glass-filled PBT), contact post length (0.122" versus 0.118"), and packaging format (Bag versus Box).

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the Würth Elektronik 61300211821 and Adam Tech RS1-02-G are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability certification.

Q: Which part should be selected for new designs?

A: Selection should be based on component availability, cost considerations, and specific mechanical requirements. Both parts are functionally equivalent for standard 2.54mm pitch board-to-board connector applications.

Q: Does packaging format affect connector performance?

A: No. Packaging format (Bag versus Box) does not affect electrical or mechanical performance. Selection is based on inventory management and handling preferences.
