AT-130(40) RF Attenuator Equivalent & Substitute Parts

Part Overview

The AT-130(40) is a fixed RF attenuator manufactured by Hirose Electric Co Ltd, rated for 30dB attenuation across 0 Hz to 18 GHz with 50 Ohm impedance and 1W power handling in an SMA in-line module package. This part is designated as Last Time Buy, indicating end-of-life status. Identifying equivalent and substitute parts is necessary to ensure continued availability for new designs, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT-130(40) are qualified based on matching the following critical parameters: attenuation value (30dB), frequency range (0 Hz ~ 18 GHz), impedance (50 Ohms), and package type (SMA In-Line Module). Power rating and compliance certifications are secondary selection criteria that may vary within acceptable operational limits.

Two substitute parts meet these core requirements:

BW-S30W2+ (Mini-Circuits): Matches all primary electrical parameters with identical attenuation, frequency range, and impedance. Offers increased power handling (2W vs. 1W), making it suitable for higher-power applications. Packaged in tube format with ROHS3 compliance.

6830.19.A (Huber+Suhner, Inc.): Parametric equivalent matching all primary electrical specifications including attenuation, frequency range, impedance, and power rating (1W). Maintains bulk packaging format consistent with the original part. REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement with identical specifications: Select 6830.19.A (Huber+Suhner). This part maintains 1W power rating and bulk packaging identical to the AT-130(40), providing the closest functional equivalent for existing designs and production processes.

For applications requiring enhanced power handling: Select BW-S30W2+ (Mini-Circuits). The 2W power rating provides operational margin in high-power RF circuits. This part is actively manufactured and carries ROHS3 compliance, supporting long-term supply chain stability.

Both substitute parts satisfy the core electrical requirements (30dB attenuation, 0-18 GHz frequency range, 50 Ohm impedance, SMA in-line module package) and are suitable for direct substitution in circuit applications where the AT-130(40) is specified.

Frequently Asked Questions (FAQ)

Q: Can BW-S30W2+ replace AT-130(40) in existing designs? A: Yes. BW-S30W2+ matches all critical electrical parameters (attenuation, frequency range, impedance, package type). The increased 2W power rating is backward compatible with 1W-rated circuits. Mechanical compatibility with SMA connectors is identical.

Q: What is the difference between bulk and tube packaging? A: Bulk packaging (AT-130(40) and 6830.19.A) is supplied in loose quantities suitable for high-volume manufacturing. Tube packaging (BW-S30W2+) provides individual component protection in reel format, typically preferred for automated assembly processes.

Q: Are there compliance differences between the substitute parts? A: AT-130(40) is RoHS Compliant. BW-S30W2+ is ROHS3 Compliant (more stringent). 6830.19.A compliance status is not specified in available data. For applications requiring specific RoHS certification levels, verify compliance documentation with the manufacturer.

Q: Why is AT-130(40) marked as Last Time Buy? A: Last Time Buy designation indicates the manufacturer has discontinued production. Existing inventory is available for final orders only. Substitution with active-status parts (BW-S30W2+ or 6830.19.A) is recommended for new designs and long-term supply assurance.

Q: Can these parts be used interchangeably in RF circuits? A: Yes, within the specified electrical parameters. All three parts provide 30dB attenuation across 0-18 GHz at 50 Ohm impedance in SMA in-line module configuration. Circuit performance is determined by these matched parameters.
