P1602AAL61 Equivalent & Substitute Parts

Part Overview

The P1602AAL61 is an active SIDACtor® thyristor transient voltage suppressor manufactured by Littelfuse Inc., designed for overvoltage protection applications requiring high peak pulse current handling. This component operates as a bidirectional TVS device with dual-element configuration in a TO-220 Modified package. The part is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when packaging or inventory considerations necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P1602AAL61 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part P1602AAL maintains identical specifications for voltage ratings (breakover, off-state, and on-state), peak pulse current ratings (both 8/20µs and 10/1000µs waveforms), hold current, element count, capacitance values, and physical package configuration. The primary distinction between the main part and substitute is packaging format: P1602AAL61 is supplied in tape-and-reel format, while P1602AAL is supplied in bulk packaging. Both parts share the same SIDACtor® series designation, TO-220 Modified package footprint, and compliance certifications. Substitution is valid when packaging format does not constrain assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

Both P1602AAL61 and P1602AAL are active products from Littelfuse Inc. with identical electrical performance and mechanical compatibility. Selection between these parts depends solely on assembly process requirements and packaging constraints. The P1602AAL61 in tape-and-reel format is suitable for automated pick-and-place assembly operations. The P1602AAL in bulk packaging is appropriate for manual assembly or when tape-and-reel format is not required. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring equivalent environmental and regulatory performance. No electrical or thermal derating is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can P1602AAL be used as a direct replacement for P1602AAL61?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (tape-and-reel versus bulk). Substitution is valid when assembly equipment can accommodate bulk packaging.

Q: Are there any voltage or current rating differences between these parts?

A: No. Both parts share identical breakover voltages (95V, 190V), off-state voltages (65V, 130V), on-state voltage (4V), peak pulse currents (150A at 8/20µs, 45A at 10/1000µs), and hold current (150mA).

Q: Do both parts fit the same PCB footprint?

A: Yes. Both use the 3-SIP package configuration with TO-220 Modified supplier device package, ensuring identical through-hole mounting compatibility.

Q: What is the significance of the dual voltage ratings (95V/190V and 65V/130V)?

A: These represent the bidirectional thyristor characteristics. The device operates with two breakover voltage levels and two off-state voltage levels, corresponding to the dual-element configuration for protection in both polarities.

Q: Are compliance certifications identical between both parts?

A: Yes. Both parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity), ECCN EAR99, and HTSUS 8541.30.0080 classification.

Q: Which part should be selected for high-volume automated assembly?

A: P1602AAL61 in tape-and-reel format is optimized for automated pick-and-place equipment. P1602AAL in bulk packaging is suitable for lower-volume or manual assembly processes.
