Engineering Selection Recommendations

All substitute parts are manufactured by Littelfuse Inc. and maintain ROHS3 compliance and EAR99 classification. Selection should prioritize active product status parts to ensure long-term availability and supply chain continuity.

For Cut Tape packaging: V130LS20AP (LS series, 4788 pcs available) or V130LT20AP (LT series, 2719 pcs available) provide the highest inventory levels for manual assembly operations.

For Tape & Reel packaging: V130LS20APX2855 (LS series, 997 pcs) and V130LT20APX2855 (LT series, 1018 pcs) support automated assembly with standard reel configurations. V130LU20AP (LU series, 1103 pcs) offers alternative series availability in Tape & Reel format.

All parts carry MSL Level 1 (Unlimited) moisture sensitivity rating and operate across the identical temperature range of -55°C to 85°C.

Frequently Asked Questions (FAQ)

Q: Can V130LS20A be directly replaced with V130LS20AP? A: Yes. V130LS20AP is a direct substitute with identical electrical and mechanical specifications. The difference is packaging format (Cut Tape vs. original disc format) and active product status.

Q: What is the difference between LS, LT, and LU series variants? A: All three series (LS, LT, LU) maintain identical electrical parameters and physical form factor for the V130 205V varistor. Series designation represents internal design variants within Littelfuse's product line. Selection between series does not affect circuit performance when electrical specifications match.

Q: Which packaging format should I select? A: Cut Tape (CT) packaging is suitable for manual assembly and lower-volume applications. Tape & Reel (TR) packaging with designations APX10 and APX2855 supports automated pick-and-place assembly. Selection depends on manufacturing process requirements, not electrical performance.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts carry ROHS3 compliance certification and are REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Why is the original V130LS20A marked as obsolete? A: Obsolete status indicates the part is no longer in active production. Active substitute parts with identical specifications are available to support ongoing designs and procurement needs.
