Substitute Part Grouping Explanation

The HCTC-30-2.3 manufactured by Signal Transformer qualifies as a direct substitute based on the following critical parameters:

• Inductance value: 30 mH @ 1 kHz (identical)
• Number of lines: 2 (identical)
• Current rating: 2.3A maximum (identical)
• DC resistance: 330mOhm maximum (identical)
• Operating temperature range: -55°C ~ 105°C (identical)
• Mounting type: Through Hole (identical)
• Package configuration: Vertical, 4 PC Pin (identical)
• RoHS compliance: ROHS3 Compliant (equivalent)

Both parts maintain identical electrical performance specifications and mechanical form factors, enabling direct substitution in applications requiring these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 8109-RC and HCTC-30-2.3 maintain Active product status with equivalent RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability, packaging format (Bulk versus Tray), and board layout constraints. The HCTC-30-2.3 features a reduced width dimension (0.600" versus 0.800"), which may provide advantages in space-constrained applications while maintaining identical electrical performance and pin configuration.

Frequently Asked Questions (FAQ)

Q: Can the HCTC-30-2.3 be used as a direct replacement for the 8109-RC?

A: Yes. Both parts share identical inductance (30 mH @ 1 kHz), current rating (2.3A), DC resistance (330mOhm), operating temperature range (-55°C ~ 105°C), and through-hole mounting configuration with vertical 4-pin packaging.

Q: What is the primary dimensional difference between these parts?

A: The HCTC-30-2.3 has a width of 0.600" compared to the 8109-RC width of 0.800". Both maintain the same length (1.350") and height (1.450"), allowing substitution in most PCB layouts with potential space savings.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS3 compliant and REACH unaffected. No compliance disadvantage exists when substituting either part.

Q: What packaging formats are available?

A: The 8109-RC is supplied in Bulk packaging, while the HCTC-30-2.3 is supplied in Tray packaging. Selection depends on procurement and assembly requirements.
