Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1982981 is based on the following critical parameters that must align between the main part and substitute candidates:

• Number of Positions: 3 positions (fixed requirement)
• Pitch: 0.197" (5.00mm) center-to-center spacing (fixed requirement)
• Mounting Type: Through-hole termination (fixed requirement)
• Manufacturer: Phoenix Contact (same manufacturer ecosystem)
• RoHS Compliance: RoHS Compliant status maintained
• Electrical Ratings: Current and voltage specifications within acceptable ranges for the application
• Operating Temperature Range: -40°C to 100°C compatibility
• Moisture Sensitivity: MSL 1 (Unlimited) classification

The substitute part 1836586 (CCA 2,5/ 3-G P20 THR R32) meets these core substitution criteria as an active production alternative within the Phoenix Contact COMBICON CCA series.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1836586 is the designated substitute for the obsolete 1982981 based on the following engineering criteria:

Product Status Alignment: The 1836586 maintains active production status within the Phoenix Contact COMBICON CCA series, ensuring long-term availability and supply chain continuity compared to the discontinued 1982981.

Compliance and Certification: Both parts maintain RoHS Compliant status and MSL 1 (Unlimited) moisture sensitivity classification, ensuring regulatory and environmental compatibility in existing and new applications.

Electrical and Mechanical Compatibility: The substitute part preserves the critical 3-position configuration with 0.197" (5.00mm) pitch spacing and through-hole mounting architecture. The 1836586 provides documented electrical ratings (12A IEC / 16A UL at 320V IEC / 300V UL) and operating temperature range (-40°C to 100°C), establishing functional equivalence for standard industrial terminal block applications.

Series Continuity: Both components are Phoenix Contact products, maintaining design philosophy and connector ecosystem compatibility within the manufacturer's product portfolio.

Frequently Asked Questions (FAQ)

Q: Can the 1836586 directly replace the 1982981 in existing PCB designs?

A: Yes, the 1836586 is mechanically and electrically compatible as a direct substitute. Both parts share identical 3-position configuration, 0.197" (5.00mm) pitch spacing, and through-hole mounting requirements. PCB footprints designed for the 1982981 will accommodate the 1836586 without modification.

Q: What is the primary reason for substitution?

A: The 1982981 is classified as obsolete and no longer in active production. The 1836586 is the active Phoenix Contact equivalent, ensuring component availability for repairs, maintenance, and new designs requiring this terminal block specification.

Q: Are there packaging differences between these parts?

A: The 1982981 packaging is not specified in available documentation. The 1836586 is supplied in Tape & Reel (TR) packaging, which is standard for high-volume industrial applications and provides improved handling and automated assembly compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1982981 and 1836586 are RoHS Compliant and classified as MSL 1 (Unlimited), meeting identical environmental and regulatory requirements for industrial and commercial applications.

Q: What electrical specifications should be verified for application compatibility?

A: The 1836586 provides IEC ratings of 12A at 320V and UL ratings of 16A at 300V. Applications using the obsolete 1982981 should verify that their electrical requirements fall within these specifications to ensure proper substitute performance.

Q: Is the 1836586 suitable for high-temperature applications?

A: The 1836586 operates across the -40°C to 100°C temperature range, which is standard for industrial terminal block applications. Applications requiring operation outside this range require separate evaluation.
