A3C-4DA-2DSC Equivalent & Substitute Parts

Part Overview

The A3C-4DA-2DSC is a 4-position rectangular receptacle connector manufactured by Hirose Electric Co Ltd, designed for board-to-board or cable applications. This connector features a 0.079" (2.00mm) pitch, through-hole solder termination, and gold-plated mating contacts rated for 1A at 200VAC. The main part is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A3C-4DA-2DSC is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (4)
• Pitch specification (0.079" / 2.00mm)
• Number of rows (2)
• Row spacing (0.079" / 2.00mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Contact finish - mating (Gold)
• Current and voltage ratings (1A, 200VAC)
• Operating temperature range (-55°C ~ 85°C)
• Flammability rating (UL94 V-0)

The identified substitute part A3C-4DA-2DSC(71) maintains identical electrical and mechanical specifications while differing in product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The A3C-4DA-2DSC(71) is the direct substitute for the obsolete A3C-4DA-2DSC. Both parts are manufactured by Hirose Electric Co Ltd within the A3 series and maintain identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, mounting method, and performance ratings.

The primary distinction between the main part and its substitute is product status and regulatory compliance. The A3C-4DA-2DSC(71) is classified as active and carries ROHS3 compliance certification, whereas the original part is obsolete and RoHS non-compliant. For new designs or ongoing procurement requiring regulatory compliance, the A3C-4DA-2DSC(71) is the appropriate selection. The substitute is supplied in tray packaging, which differs from the bulk packaging of the original part but does not affect functional compatibility.

Both parts share identical moisture sensitivity level (MSL 1), REACH status, and export classification (EAR99), confirming full interchangeability for applications requiring the A3 series 4-position rectangular receptacle connector with 2.00mm pitch and gold-plated contacts.

Frequently Asked Questions (FAQ)

Q: Can A3C-4DA-2DSC(71) be used as a direct replacement for A3C-4DA-2DSC?

A: Yes. The A3C-4DA-2DSC(71) is a direct substitute with identical electrical and mechanical specifications. All critical parameters including connector type, position count, pitch, mounting type, termination method, current rating, voltage rating, and operating temperature range are equivalent.

Q: What is the difference between the two parts?

A: The primary differences are product status and regulatory compliance. The A3C-4DA-2DSC is obsolete and RoHS non-compliant, while the A3C-4DA-2DSC(71) is active and ROHS3 compliant. The substitute is also supplied in tray packaging rather than bulk packaging.

Q: Does the packaging difference affect compatibility?

A: No. Packaging format does not affect the connector's electrical or mechanical performance. The tray packaging of the A3C-4DA-2DSC(71) is a supply chain consideration only and does not impact functional interchangeability.

Q: Are there any compliance considerations when switching to the substitute?

A: The A3C-4DA-2DSC(71) carries ROHS3 compliance certification, making it suitable for applications subject to RoHS regulations. The original part is RoHS non-compliant. For designs requiring regulatory compliance, the substitute is the appropriate choice.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is determined by equivalence in connector type (receptacle), position count (4), pitch (0.079" / 2.00mm), row configuration (2 rows with 0.079" spacing), mounting type (through hole), termination (solder), contact finish (gold), current rating (1A), voltage rating (200VAC), operating temperature range (-55°C to 85°C), and flammability rating (UL94 V-0).
